Eventuelt kan me-talltåkepartiklene bestå av et metallisk reduserende middel som utgjøres for eksem- According to main patent no. 100,084, the welding agent consists of solid particles of a metal oxide-containing base material in which in each individual particle there are microscopic small inclusions of metal obtained by reducing the metal oxides in the base material evenly distributed as a dispersion through the base material. Typically, the solid particles have a size range from 4.76 mm to 0.04 mm, and the metal mist particles suspended therein have a size range from 2.5 to 250 microns. Optionally, the metal mist particles can consist of a metallic reducing agent which is, for example,

Oppfinnelsen angår også en fremgangsmåte til fremstilling av et slikt sveisemid- The invention also relates to a method for producing such a welding agent
del hvilken omfatter smeltning av bestemte mengder talk og kvartssand og de industrielle biprodukter ferromanganslagg og ferrovanadinslagg og at slikt materiale en- part which includes the melting of specific quantities of talc and quartz sand and the industrial by-products ferromanganese slag and ferrovanadine slag and that such material en-
ten før smeltingen eller som en sen ovnstilsetning tilsettes en blanding av bestemte mengder kalsiumfluorid og det metalliske desoksydasjonsmiddel samt helling av den smelteed masse i vann og knusing av de størknede produkter. before the melting or as a late addition to the furnace, a mixture of specific amounts of calcium fluoride and the metallic deoxidizer is added, as well as pouring the molten mass into water and crushing the solidified products.
Et middel som er fremstilt av uteluk-kende naturlige mineral og industrielle biprodukter danner ikke et middel som kan anvendes for sveising, da det vil ha oksy-derende egenskaper. Et slikt middel vil dessuten ha en uheldig innvirkning på svei-sens metallurgi og kommer til å gi porøsitet og andre ikke ønskede defekter. For å fremstille et middel av disse materialer hvilket er tilfredsstillende for sveising er det nød-vendig å tilsette smeiten et desoksyderende materiale. An agent that is made exclusively from natural minerals and industrial by-products does not form an agent that can be used for welding, as it will have oxidizing properties. Such an agent will also have an adverse effect on the metallurgy of the weld and will produce porosity and other unwanted defects. In order to produce an agent of these materials which is satisfactory for welding, it is necessary to add a deoxidizing material to the melt.
En blanding av kalsiumfluorid og 85 pst. ferrokisel tjener til fullstendig å des-oksydere midlet og etterlater desoksyderende «metalltåke» i den størknede blanding slik at denne tjener som desoksyderingsmiddel når sveisemidlet deretter anvendes ved sveising. Andre metalliske desoksyderingsmidler slik som ferromangan og kiselmetall kari anvendes som en erstatning for ferrokisel uten at man derved går uten-for oppfinnelsens ramme. En typisk ovncharge for svesiemidlet ifølge foreliggende oppfinnelse er følgende: A mixture of calcium fluoride and 85 per cent ferrosilicon serves to completely deoxidize the agent and leaves deoxidizing "metal mist" in the solidified mixture so that this serves as a deoxidizing agent when the welding agent is then used in welding. Other metallic deoxidising agents such as ferromanganese and silicon metal karium are used as a substitute for ferrosilicon without thereby going outside the scope of the invention. A typical furnace charge for the welding agent according to the present invention is the following:
Ifølge en utførelse av foreliggende fremgangsmåte smeltes en hovedcharge som består av talk, tørr kvartssand, ferromanganslagg og ferrovanadiumslagg i en elektrisk ovn ved fra 1260 til 1650° C. Når chargen er fullstendig smeltet, tilsettes kalsiumfluorid og ferrosilisium i ovnen. FeSi kan tilsettes sammen med kalsiumfluoridet i den chargen, men de beste re-sultater oppnås når FeSi og CaF2 tilsettes som en sen ovnstilsetning. Tilsetningen av disse materialer har en tendens til å senke smeltens temperatur til omkring 1230 til 1510° C. Så snart den sene tilsetningen er smeltet og fullstendig blandet i smeiten, helles smeiten i vann. Deretter males denne til passe størrelse for sveisemidlet. According to one embodiment of the present method, a main charge consisting of talc, dry quartz sand, ferromanganese slag and ferrovanadium slag is melted in an electric furnace at from 1260 to 1650° C. When the charge is completely melted, calcium fluoride and ferrosilicon are added to the furnace. FeSi can be added together with the calcium fluoride in that charge, but the best results are obtained when FeSi and CaF2 are added as a late furnace addition. The addition of these materials tends to lower the temperature of the melt to about 1230 to 1510° C. As soon as the late addition is melted and completely mixed in the melt, the melt is poured into water. This is then ground to the right size for the welding agent.
Tilfredsstillendes blanding av smeiten kan oppnås ved å utelate en liten del om-trent 4 pst. av talk fra begynnelseschargen og tilsette resten senere sammen med ferrosilisium og kalsiumfluorid. Ved den nevnte fremgangsmåte må den anvendte talk være gassavgivende og består vesent-lig av MgO . SiO,,. C02. Når den tilsettes i ovnen drives C02 bort. Utdrivning av gass-formig COa fra denne talkandel i den sene ovnstilsetningen, fremkaller tilstrekkelig omrøring i smeiten for fullstendig å for-dele metalldesoksyderingsmidlet i blandin-gen. Når ovnen imidlertid tillater mekanisk omrøring av smeiten, kan all talk gå inn i begynnelseschargen og talken kan være av en type som ikke er gassavgivende. Satisfactory mixing of the melt can be achieved by omitting a small portion of about 4 percent of talc from the initial charge and adding the remainder later along with ferrosilicon and calcium fluoride. In the aforementioned method, the talc used must be gas-releasing and consists essentially of MgO. SiO,,. C02. When it is added to the oven, C02 is driven away. Expulsion of gaseous COa from this talc portion in the late furnace addition induces sufficient stirring in the melt to completely distribute the metal deoxidizer in the mixture. However, when the furnace permits mechanical stirring of the melt, all the talc may enter the initial charge and the talc may be of a non-gassing type.
Tilsetning av kalsiumfluorid sammen med det metalliske desoksyderingsmateri-ale som en sen ovnstilsetning, tjener flere formål. Først og fremst smelter kalsiumfluoridet, som har relativt lavt smeltepunkt, og danner et beskyttelsesdekke over de metalliske desoksyderende partikler og beskytter disse slik at de ikke smelter og løper sammen i smeiten. Videre senker kalsiumfluoridets relativt lave smeltepunkt smeltens smeltepunkt slik at når sammensetningen anvendes ved sveising, er flussmidlet mer flytende og gir derved en jev-nere flate på sveisen og forbedrer bindin-gen med grunnmaterialet. Det er imidlertid å foretrekke at kalsiumfluoridet og metallisk desoksyderingsmiddel tilsettes som en sen ovnstilsetning slik at de flyktige fluori-der ikke tapes fra sammensetningen. Det beste resultat oppnås når smeiten helles ut i vann så snart dette er praktisk etter tilsetning av kalsiumfluorid og metallisk desoksyderende stoff. Adding calcium fluoride along with the metallic deoxidizing material as a late furnace addition serves several purposes. First of all, the calcium fluoride, which has a relatively low melting point, melts and forms a protective covering over the metallic deoxidizing particles and protects them so that they do not melt and run together in the smelting. Furthermore, calcium fluoride's relatively low melting point lowers the melt's melting point so that when the composition is used in welding, the flux is more liquid and thereby provides a smoother surface on the weld and improves the bond with the base material. However, it is preferable that the calcium fluoride and metallic deoxidizing agent are added as a late furnace addition so that the volatile fluorides are not lost from the composition. The best result is obtained when the melt is poured into water as soon as practical after adding calcium fluoride and metallic deoxidizing agent.
Når bestanddelene blandes og smeltes i en elektrisk ovn i de i ovenstående tabell angitte mengdeforhold, uthelles i vann. og oppmales til passe størrelse, er det fremstilt et sveisemiddel for pulverdekket lysbuesveising og inneholdende metalltåke-desoksyderingsmiddel. En kjemisk analyse av. midlet ifølge foreliggende oppfinnelse fremgår av følgende tabell: When the ingredients are mixed and melted in an electric furnace in the proportions indicated in the table above, they are poured into water. and ground to the right size, a welding agent for powder-coated arc welding and containing a metal mist deoxidizer has been produced. A chemical analysis of. the agent according to the present invention appears from the following table:
Dette middel, som er sammensatt som angitt ovenfor, er blitt funnet å være ge-nerelt tilfredsstillende for anvendelse ved pulverdekket lysbuesveising av mykt karbonstål og av legert stål. Sveiseprøver er utført for å sammenligne sveisemidlet iføl-ge foreliggende oppfinnelse med en kom-mersiell blanding som er bestemt for sam-me formål. Prøven viste at midlet ifølge This agent, which is composed as indicated above, has been found to be generally satisfactory for use in powder coated arc welding of mild carbon steel and of alloy steel. Welding tests have been carried out to compare the welding agent according to the present invention with a commercial mixture which is intended for the same purpose. The test showed that the remedy according to
foreliggende oppfinnelse ga et slagg som the present invention produced a slag which
lettere kunne fjernes og en sveiseflate fullstendig fri for smeltede smeltepartikler. could be removed more easily and a welding surface completely free of molten metal particles.
Den kommersielle 'blanding som svarer til The commercial 'mixture corresponding to
midlet ifølge foreliggende oppfinnelse gir the agent according to the present invention provides
ofte smeltede metalldeler langs sveisekan-ten. Dessuten gir midlet ifølge foreliggende oppfinnelse gode sveiser på rust hvor often melted metal parts along the welding edge. In addition, the agent according to the present invention provides good welds on rust where
det kommersielle midlet i mange tilfeller the commercial remedy in many cases
gir porøsitet. Midlets forbedrede oppførsel gives porosity. The improved behavior of the agent
antas i stor grad å bero på dets høye kvarts-innhold og inneslutning av metalltåke. believed to be largely due to its high quartz content and inclusion of metal mist.
Flussmidlet ifølge foreliggende oppfinnelse kan også brukes ved høyere sveise-strømmer enn kjente midler. Ved en sveise-strøm på 1300 ampere, 30 volt vekselstrøm The flux according to the present invention can also be used at higher welding currents than known means. At a welding current of 1300 amps, 30 volts alternating current
og under anvendelse av parallelle 3,4 mm and using parallel 3.4 mm
diameter sveisetråder ga midlet ifølge foreliggende oppfinnelse utmerkede liggende diameter welding wires gave the agent according to the present invention excellent lying
kjedesveiser på myke karbonstålplater, idet chain welds on soft carbon steel plates, ie
kjente midler ga sveiser som var ru og top-pet og slaggen var ikke frittpellende. I sin known means produced welds that were rough and peaked and the slag was not free-peeling. In his
helhet gir sveisemidlet ifølge foreliggende overall provides the welding agent according to the present
oppfinnelse sveiser som hadde færre under-skjær og lokale sammentrekninger og jev-nere flater og færre gassporer sammenlig-net med hva som produseres ved hjelp av invention welds that had fewer undercuts and local contractions and smoother surfaces and fewer gas traces compared to what is produced using
kommersielle sveisemidler. Dessuten ligger commercial welding agents. Also located
dets hovedfordel like overfor tidligere kjente sveisemidler av denne type i det faktum its main advantage over previously known welding means of this type in that fact
at det er forholdsvis billig å fremstille. that it is relatively cheap to produce.
